The Chemistry of Latent Fingerprints KEY Chemical Reaction Silver nitrate (AgNO3) can react with the salt (NaCl) left from the perspiration on the friction ridge skin to form solid silver chloride (AgCl) and sodium nitrate. The silver chloride can then be converted to silver oxide (Ag2O)‚ which is dark in color and can be more easily seen. Challenge Suppose the fingerprint processing technique that uses silver nitrate to react with the salt from perspiration produced 5.8 x 10-2 grams of silver
